Puron + All-style evap coils equals junk
Moved into my newly built home 2.5 years ago...
Lennox 3.5ton condenser and filter unit with an All-style evap coil.
Evap coil GONE after only 2.5 years!
Failed on the evap coil itself where they fused the aluminum to copper
The AC guy said I can probably expect this repair AGAIN b/c the evap coil are either A. getting eatin by the new r410a oil or B. pressures are too high
Say thanks to the EPA and poor manufacturing processes for this headache (errr.. wallet-ache)
